一九七九年高等学校统一招生化学试题考了一道填空题:把烧红了的铂丝插入盛浓氯水的锥形瓶中,观察到液面上的铂丝更加红亮。反应的化学方程武是____。反应中的还原剂是____,电子转移总数是____个。结果我省绝大多数的考生因把铂丝当做参加反应的物质而写错了化学反应方程式。分析产生其错误的主要原因是因为学生没有做过氨催化氧化的实验。现在全日制十年制学校高中课本化学第一册里按排了这
In 1979, a unified college entrance examination for chemistry examinations filled a blank test question: the red hot platinum wire was inserted into a thick conical flask of chlorinated water and observed that the liquid platinum wire was even more red and bright. The chemical equation of reaction is ____. The reducing agent in the reaction is ____ and the total number of electron transfer is ____. The results of the vast majority of candidates in our province because of the platinum wire as a reaction to participate in the material and the wrong chemical reaction equation. Analysis of the main reasons for the error is because the students did not do ammonia catalytic oxidation experiments. Now a full-time 10-year school high school textbook chemistry in the first row of this
